Remove the tin from the oven and place in a desiccator until cooled to room temper temperature. ature. Weigh Weigh the tin and dried sample to the nearest 1 mg. NOTE  4—This material is usually nonhomogeneous and shall be thoroughly stirred before weighing. The weighing shall also be accomplished quickly to avoid loss of solvent by volatilization. Some vacuum ovens require a longer period of time than 15 min to reach 120°C, even after preheating. It is recommended that the operator watch closely the time requ re quir ired ed to re reac ach h 12 120° 0°C C an and, d, by ma mani nipu pulat latio ion n of th thee he heat at co cont ntro roll mechanism, minimize the amount of time required to reach 120°C while not exceed exceeding ing the requir required ed tempe temperature rature.. NOTE   5—Th 5—Thee us usee of a va vacu cuum um ov oven en is ma mand ndato atory ry fo forr dr dryi ying ng th thee specimen. This oven has neither an exposed heating surface nor an open flame, thus avoiding the danger of flashing. The oven also provides an open vacuum to exhaust solvent fumes.

6.1.2.2 After weighing, 6.1.2.2 weighing, dissolve the dried sample in THF and det determ ermine ine qua quantit ntitativ atively ely any iner inertt fille fillers rs by mean meanss of  centrifuging. Deduct the weight of the fillers determined from the weight of the dried sample prior to calculating the content of PVC resin in the cement.

NOTE  2—It is recommended that solvent cements made to this specification not be orange since that color is recommended for use with CPVC solvent cement under Specification F493 Specification F493..

NOTE  6—Dissolve most of the dried sample by adding 15 mL of THF to the sample in the ointment tin and stirring with a glass rod for 15 min. Dissolve the remainder with a second addition of 15 mL of THF, followed by a third addition of 5 mL of THF to rinse the ointment tin. Centrifuge the entire volume at 20 000 r/min for 15 min. Discard the supernatant supernatant liquid. Add 15 mL of THF to the tube, mix thoroughly, and transfer the tube contents to the ointment tin. Use 2 mL more of THF to wash down the tube, and pour into the ointment tin. Evaporate off the THF in the vacuum oven at 248°F (120°C) for 45 min. Cool in desiccator, weigh the tin to the nearest 1 mg, and calculate the percent of inert filler present in the cement.
